Are you using the PC as a gateway to the internet and a router for your local network? If so can both networks connect to the internet? I am not an expert, but you will have to add a route. I am not in front of a Linux box right now but I think you need to do a route -a 10.10.10.0 10.0.0.0. This should make it work.

HI,

First of all thanks for your reply.

Here is complete details.
Yes pc internet gateway and it is NAT (packet forwarder) for 10.0.0.1 local lan.
Recently i got net backup line from my office branch whcih is 10.10.10.54 with gateway 10.10.10.1 . NOw iam unable to ping my branch office gateway 10.10.10.1 .

How can i ?

thanks for your time.

What you are saying is the 10.10.10.x is a direct link to your office (leased or dialup doesn't matter). How is the link to your office set up? Is it router to router or is it a dialup?
